\frac{27}{x}=\frac{30}{10}
Divide both sides by 10.
\frac{27}{x}=3
Divide 30 by 10 to get 3.
27=3x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
3x=27
Swap sides so that all variable terms are on the left hand side.
x=\frac{27}{3}
Divide both sides by 3.
x=9
Divide 27 by 3 to get 9.
